'subj of King of lSw-eden, `residing atl Chil llinois, have invented certain new andu'sef fu-li 11i-proveniente @f in Separating# Mec-hanism *for Thrashers; of whichthe fol-lowing is 'a'f fulf'l,E clear-,fand Venactspe'cificationJ-ll-' vThis invent-ion relates to'fthreshingfimachines 'and7^ morefparticul'arlyto screening or separatingmechanism'for machines-Pof this character. y,

It .is important. forl theeff-freient screening and separating of 'the grainin threshing machines*that the material kbeing Vseparated be spread 4evenly-across the screen.'= Then the .threshing .machine i'stransported around. aujield ofigrailm as jis the -rcase :with the "haii-r vester thrashery: the.- uneven-ness;` of. the ground@\causes2thefmaeliine to; tilt, Vone side of the mechanism` being positionedmhigherthanx -theotheralt will he;readily;fseenlv that as one side ofthe machine is tilted upwardly,.and-thev otherlfsidesf'dciwnwa-rdly, the grain and chaff which has been deposited upon the screen of the separator will be thrownto one side of the screen, thereby7 tending to clog the screen and interfere with the eflicient separati-on of the f grain from the chaff.

lVith these difficulties in mind, the" object of the present invention is to overcome this condition, and effectv an even distribution of the grain and chaff across the screening mechanism of the separator.`

lIn the present instance, this object has been vaccomplished by the provision of means `positioned at the opposite sides of the separator for forcing the material to be separated toward the center of the upper screen, thereby evenly distributing this Inaterial.

i In the accompanying drawings yone enibodiment of my inventionhas been illustrated, and in these drawing l Fig 1 shows the rear elevation of a portion of a threshing machine, the straw carriers and a portion of the separatorvbeing illustratedV in connection with my distributing mechanism; andl L Fig.l2 is a side elevation of the construction shown in F ig. 1.

In the `drawings the usual type of straw carriers 10 have been illustrated, these carriers being operated by the crank shafts l2 of the threshing machine in Jansma.z

As the L separator mechanism 13 is oscillated in the usual manner, means 1s provided to close the opening between the separator and the walls order to prevent any grain from being thrown outwardly between these members byV the beaters 15. The means provided in the presentr in-l stance comprises shield members 25 which" f are secured to the lower edges of the walls 12 and are offset to a position adjacentvthe inner edges of the side walls -of the separator, `as clearly illustrated in' Fig.v l.`

Aw distinct advantage is 'obtained in conf v.

95 i that the speed of necting the beater shafts to the crank shafts of the straw carriersv in the beaters is always maintainedin a constant ratio with the speed of the straw Acarriers," and as the straw walkers arespeeded up the beaters will also be speeded up and will therefore `be enabled to handle an increased quantity of material,

It is believed that the operation'of thej device will be cle-ar tion`of the construction, but va brief statement 'of the operation is given below.

As is well known, the straw, grain andg from the abo-ve descripchaff is deposited on-the straw carriers-from the threshing cylinder, the straw being' gradually'l moved rearwardly and the' chaff lie and grain passing through the straw carriers being deposited on the separator mechanism. The separator mechanism is oscillated in the usual manner, the chaff being discharge-d at the rear of the machine and the grain passing through the screening mechanism and finally being delivered to the sacks.

`When the machine is used on side hills the tendency of the grain and chaffis to move to one sidevofthe separating mechanism, but the beaters 15 are rotated in the proper direction to force the grain and chaff toward the center of the separator, thereb-y effecting an even distribution of the material across lthe width of the separator.

The beater blades illustrated will act upon the grain directly and will also so direct currents of air that the chaff and grain will be blown toward the center as well as being forced toward the center by direct contact of the blades therewith.

While I have in the above specication shown and described but a single embodiment of my invention, it is to be understood that my invention is capable of modication. Changes, therefore, in the construction and arrangement of parts may be made without departing from the spirit and scope of my invention, las expressed in the appended claims.

' l. In a threshing machine, a casing, straw carriers carried by said casing, a crank shaft for operating said straw carriers, a separater,

and operatively connected with said crank shaft for evenly distributing the material to be separated across said separator.

2. In a threshing machine, a casing, straw carriers carried thereby, a crank shaft for operating said straw carriers an oscillatory separator positioned below said straw carriers, and means comprising a rotary shaft having oppositely disposed blades carried by said casing and operatively connectedy to said crank shaft for evenly distributing the material to be separatedacross said sep-arator.

3. In a threshing machine, a screen, straw carriers positioned above said screen, a crank shaft for operating said straw car-l riers,` andy rotary beaters operatively connected to said crank shaft for evenly distributing the material to be operated upon across said screen. f 1

Il. In a threshingv machine, a screen, straw located below said carriers and a recarriers positioned above said screen, a

crank shaft for operating said straw carriers, and a rotary beater operatively connected to said crank shaft and comprising oppositely disposed blades extending longitudinally with respect to said machine for distributing the material to be operated upon across said screen. y

In testimony whereof I affix my signature.
